How Does Underdog Predict Work?
Underdog Predict is a prediction-market exchange, not a sportsbook. On Underdog Predict (also known as UDX at underdogexchange.com), users buy or sell contracts tied to a real-world NBA outcome, or several other markets. Each contract’s market price directly reflects the implied probability of that specific outcome occurring. Prices move dynamically as other participants trade on the market, and you can choose to hold your positions until the event officially settles.
Because this operates as an exchange, there is no house taking the other side of your position. You trade exclusively against other market participants, and UDX serves as a regulated venue subject to CFTC regulatory oversight rather than operating under state gaming licenses. Trading involves risk, including total loss on positions, and nothing on the platform constitutes a recommendation, solicitation, or offer to buy or sell any financial instrument.
Where Can You Trade With Underdog Predict?
Availability is limited to participating states where UDX operates, and eligible users must also meet the minimum age requirement.
Some states are strictly excluded from access, so the definitive, current list of participating and excluded states is displayed during the sign-up process and directly on underdogexchange.com. Users should always confirm their eligibility there before making a deposit to fund their account.
The regulatory status of prediction markets is being actively contested in some states. Because legal challenges and regulatory reviews are currently ongoing, state availability can change at short notice.
